Rainy weather can disrupt solar or off-grid charging systems, leading to inconsistent charging cycles. Undercharging promotes sulfation, while overcharging (due to erratic solar input) can cause excessive gassing and water loss.
Best Practices:
- Use Smart Chargers: Modern charge controllers with adaptive algorithms adjust for weather variations.
- Implement Equalization Charges: Periodic controlled overcharging helps dissolve sulfate crystals.
- Monitor State of Charge (SoC): Use battery monitors to prevent deep discharges.
A disciplined charging routine compensates for environmental challenges.
